Orbot configuration invaldid

Hi Everyone

Im using a Murena two with up-to-date software.

Since about two weeks, the “Hidden IP”-Function in the Advanced Privacy Application doesn’t seem to work anymore.
In the past, a reboot/turn off-turn on did the trick.
But, as I mentioned, since about two weeks, as soon as i unlock the phone for the first time after restart, it immediately says “orbot configuration invalid” at the bottom of the screen.

Is this a User-Fault? Or a Software-issue?
